I have a 1991 honda civic CRX DX I am currently putting in a 1993 Integra GS B18A1. I bought the whole car to due the swap from.I want to put a header on the B18 when I put it in the CRX. My question is what header will work? A header for the Acura Integra GS? And will it bolt to the existing Crx cat and exhaust system? Also will the power steering rack from the 1993 Integra work in the 1991 Crx DX? Thanks for any help!!
